The Shen Research Lab focuses on engineering biomaterials and using these materials to investigate cell-microenvironment interactions and to model diseases, with ultimate goals of understanding, detecting, and curing human diseases. The ongoing projects include a topographically patterned material platform to study Duchenne Muscular Dystrophy (DMD) and Congenital Muscular Dystrophy (CMD), a nanoparticle platform for antiviral therapy, and oxygen-releasing materials for cell-based therapy.


Research Summary/Interests

Engineering of Biomaterials and Cellular Microenvironments, Cell-Environment Interactions, Biomolecular Engineering


We are interested in molecular engineering of novel biomaterials and investigation of structure-property-function relationships of these materials. The applications of these materials include tissue regeneration, stem cell fate regulation, drug delivery, and imaging contrasts. The biomaterials we are developing are based on chemically synthesized polymers and biosynthesized protein-polymers. We harness unique and smart characteristics of protein domains and use them as building blocks that serve as carriers, bioactive motifs, and structural components.

Tissue Engineering and Artificial Stem Cell Niches

Regenerative medicine holds a big promise to cure many human diseases. The advances in stem cell biology provide unlimited and even patient-specific stem cell sources to create functional tissues and disease models. The success of the field relies on our ability to provide instructive extracellular environmental cues to guide cell behavior and fate selection. We use the novel biomaterials engineered in our laboratory, in combination with the concepts derived from developmental biology and microfabrication technologies, to build precisely controlled artificial niches to guide stem cell fate selection and tissue regeneration.

Drug Delivery

Cancer is the second leading cause of death in the United States. Although numerous drugs with potent anticancer activities have been found, attempts to convert laboratory results into clinical interventions have limited success. Such unfortunate outcome is largely due to lack of optimized drug carriers. Ideal carriers for anticancer drugs should have targeting ability to bring drugs exclusively to cancer cells while keeping healthy cells unaffected. In addition, the size of the carriers should be controlled so that they are large enough to avoid rapid clearance in kidney but small enough to cross blood vessels and move through the interstitial space of solid tumors to access all malignant cells. Drug carriers lacking efficient targeting ability and proper sizes lead to severe toxic side effects and failure to eradicate cancer cells. We are developing novel targeted nanocarriers for anticancer drugs to enhance the efficacy and safety of cancer treatments.
